Unsuspended

Surly's Krampus rolls fast, holds speed, and devours corners. Surly built its Boosted frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. The 29 x 3-inch Dirt Wizard tires on 40mm Alex rims take your trail ride to new heights of fun. These big tires offer increased traction, incredible float, and reduce the need for suspension because the large volume is plenty to smooth the trail. You'll also get a SRAM NX 1x drivetrain, Answer Pro Taper bars, and SRAM Level hydraulic brakes to make you the new master of terrain that used to be out of bounds.

Years ago the Karate Monkey helped start the 29-inch wheel movement and, as time's gone by, many companies ­– Surly included – have experimented with even more wheel sizes.
With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29-inch wheel, yet you get all the traction and floatation benefits of extra-wide knobbies. And that's just the tires.
The Karate Monkey frame has recently gotten a makeover that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on Surly's Instigator 2.0, and a slight tweak in geometry that is more progressive and trail-oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29-inch wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled.
- 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube
- Adjustable rear dropouts with 145mm Gnot-Boost spacing. Works with 142, 148 12mm thru, as well as 135mm w/ 10/12 washer
- Internal dropper seatpost routing with 30.9mm seat tube ID
- Clearance for 29 x 2.55 or 27.5 x 3 tires

The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142x12mm thru axle if that's your schtick, but this rig comes with a 135mm QR hub, snug as a bug with a pair of adapter washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, and a Surly Moloko Bar gives your hands damn near as many options as well, so they stay clappably happy even on your longest, story-generating adventures.

Going fat isn't just a fun way to ride—it's a ride revolution. The security and control that the wheel system, found on our Fatboy, provides is unparalleled. You get dramatically more traction, grip, and floatation than with traditional mountain tires, all without sacrificing much to climbing efficiency.
The end result is easy to explain—you have way more fun. And to make sure of it, we built the Fatboy with a durable list of components that are low-maintenance and eager to perform season after season. Have more fun—go fat.
- The frame features an M5 alloy construction that provides the ideal blend of efficiency and durability, while the geometry creates a roomy top tube and short chainstays for easy climbing and confident descending.
- A FACT carbon fiber fork provides tons of compliance and absorbs chatter, while simultaneously keeping the overall weight of the bike down.
- The SRAM NX one-by groupset keeps things simple, and is ready to take on the trail for the long haul.

The ECR is Surly's answer to those times when you just need to escape to the woods for a while to get away from the humdrum of life. Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, Surly redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as Surly is offering that size in both options.
Other updates to the ECR include and are limited to: Gnot-Boost rear spacing and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 29+ sizes have two water bottle mounts and one set of Three-Pack bosses. You’ve got lots of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it.

Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of their other Omniterra bikes can, but they borrowed elements from both their Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish when you have to ride back to the top. It also has the chops for any sort of expedition you may want to undertake. It has plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube; standard bottle mounts on the seat tube and underside of the down tube; plus rack mounts on the frame and fork and fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. Wednesday also has its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm. Wednesday gives you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8? tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6? tires on an 80mm rim. Wednesday is made out of Surly's own proprietary 4130 CroMoly steel and is ED coated for extra protection from the elements.

If you’re like us, your bike needs will likely change by the day, week, month, or year. Ogre can get you to your job during the week, then way out of town on the weekend. The latest version of the Ogre has received some fantasitic updates, including horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefier tire clearance — all in a 29er platform. The Ogre features Surly's Moloko handlebar offering hand positions that you didn’t even know existed and the ability to mount even more accessories. Ride it any day of the week; it’s not sluggish on pavement or gravel and can also hold its own on singletrack.
- Gnot-Boost spacing allows the use of 135mm QR hub, 142 x 12mm thru-axle, or 148 x 12mm Boost hubs.
- Full-length Surly Trip Guide housing line guides for derailleurs and brakes
- Two sets of bottle cage mounts
- Disc and rim brake compatible with removable post cantilever pivots
- Upper seatstay threaded barrels with mid- and low-blade fully threaded through-blade fork eyelets
- Threaded holes for racks, fenders, and trailer mounting nuts
- Rohloff OEM2 axle plate mounting slot
- Tire clearance for 29 x 2.5” or 27.5 x 3”

The venerable Karate Monkey. When it comes to mountain riding, this bike brings everything you need to the experience and more. It's shod with 27.5 x 3.00 terrain-clawing Dirt Wizards for max traction on singletrack thanks to an aggressive tread pattern and cushy, wide footprint. But there's more to this agile trail runner's set of shoes — thanks to generous frame clearance, you can drop a set of 29-inch wheels in with up to a 2.50-inch tire if you desire something with less bite and similar roll-over capabilities. And, with Surly's Gnot Boost rear dropout spacing, you can comfortably run any kind of mountain bike hub: 10 x 135mm QR, 12 x 142mm, or 12 x 148mm Boost will all work in the Karate Monkey frame. Wheel choices aside, Surly built the updated Karate Monkey with a nod toward modern trail-bike geometry and includes internal dropper post routing, two or three bottle mounts (depending on size), threaded fender eyelets, and all the braze-ons you've come to expect from Surly for attaching racks, cages, and bags galore. Running gear consists of SRAMS's rock-solid NX 1x11 drivetrain with full-length external housing and Level hydraulic disc brakes for reliability when you need it most. Throw on a 140mm suspension fork and this all-rounder turns into a serious trail slayer. For what seems like a simple bike at first glance, the Karate Monkey offers much, much more. Listen to the Monkey and lose yourself in its ways.

The Surly Lowside is the bike that gets you across town for a quick rip on singletrack, then over to the bar for a night out. It’s the bike you turn to when you’re not entirely sure what the night has in store. It’s the bike to grab when you want to have just as much fun riding to the trail as you do on the trail, itself. Singlespeeding is an integral part of Surly’s DNA, and the Lowside continues the tradition, by taking a simpler approach to trail riding.
- 100% Surly 4130 chromoly frame, main triangle is double-butted; 1 1/8" threadless chromoly fork
- Singlespeed "specific" (derailleur hanger: yes; Trip Guides: no)
- Dropper post routing
- Gnot-Boost rear spacing
- Front and rear thru-axles
- 26 x 3" or 27.5 x 2.8" tire clearance

When your bike touring route takes you over the river and through the woods with a quick jaunt through town for supplies, you can't beat the versatility and smooth riding characteristics of Surly's new Bridge Club. First off, it's a Surly so you know the 'Natch chromoly steel frame and fork are built to handle your entire kit and caboodle, and thanks to the typical overabundance of rack and cage provisions you can mount your gear via traditional racks and panniers, go full bikepacking-style, or mix-up your favorite combo of the two. The Bridge Club rolls on plump 27.5 x 2.4-inch WTB Riddler tires for a blend of low rolling resistance on smooth pavement and confident handling on forest trails. You can also run up to a 2.8-inch wide tire for more flotation, or swap-in a 700c wheel and tire combo if your route includes a lot of on-road riding. A dependable 2x10 drivetrain ensures you'll never run out of gears as you make the push up long climbs, and mechanical disc brakes offer worry-free performance to keep you safe no matter what the weather brings. And, thanks to fully housed cabling and front and rear fender mounts, you can splash through soggy days with a smile. A comfortable Salsa Bend flat bar and WTB Volt saddle complete this relaxed all-terrain tourer.

Surly's Krampus rolls fast, holds speed, and devours corners. It's designed for 29 x 3-inch tires, offering increased traction, incredible float, huge rollover, and low-fi suspension to take your trail ride to new heights of fun. Surly built this frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. Boost front spacing keeps you current with the latest MTB tech, and, "Gnot Boost," rear spacing means you can run any the rear hub you want: 135 x 10 QR, 142 x 12mm, or 148 x 12mm thru axles. This frameset also offers internal dropper post routing so you're granted a license to get rowdy, which you really can't help but do on a Krampus.

The beach, the nordic ski zone, that ribbon of singletrack that disappears through the woods—Specialized’s Hellga loves all of the above. This lightweight aluminum frame and fork ride on 4.6-inch Ground Control tires that simply float above anything in your path. The super-wide aluminum rims give you stability and durability to roll through the rockiest, root-filled trails like butter. SRAM’s X5 hill-topping 2X10 drivetrain provides slick shifting on all-day adventures or snowy cruises. And, you can bring it all back down to earthly limits thanks to the Tektro Aries disc brakes. Plus, the Specialized aluminum bar, stem, and post have the all-season durability needed for a bike this capable.

The Ogre can get you to your job during the week, then way out of town on the weekend. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre has many of the same features as Troll — horizontal slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance — but in a 29er platform.
- Surly 4130 chromoly steel, main triangle double-butted frame
- TIG-welded, Horizontal slotted with derailleur hanger, Gnot-Boost spacing allows the use of 135mm QR hub, 142 x 12mm thru-axle or 148 x 12mm Boost hubs. Features Rohloff torque arm slot and threaded eyelets for fenders, racks and Surly trailer mounts
- Full-length Surly Trip Guide housing line guides for derailleurs and brakes; two sets of bottle cage mounts; upper seatstay threaded barrels, mid- and low-blade fully threaded through-blade fork eyelets; threaded holes for racks, fenders and trailer mounting nuts; Rohloff OEM2 axle plate mounting slot
- Disc brakes only. Disc mounts are 51mm IS. Note: rear disc brake is limited to 160mm maximum rotor diameter and requires the use of Surly caliper adaptor (included with frames and bikes)
- Frame is ED coated for increased life expectancy
- Tire clearance for 29 x 2.5” or 27.5 x 3”

If you’re like us, your bike needs will likely change by the day, week, month or year. Ogre will get you to your job during the week, then way out of town on the weekend. It even has the chops to handle a cross-country trek or nine. It’s not sluggish on pavement or gravel and can also hold its own on singletrack. Ogre is designed to be the ultimate steel utility vehicle. It relishes in those “take-the-long-way-home-and-find-some-beverages-along-the-way” sort of commutes. You can also haul enough crap on it that you don’t even have to go home if you don’t want to.
For this year, we simplified Ogre a bit. We removed the canti studs, so it is now a disc brake-only beast. Now, before you start yelling at us about how the canti studs were the only reason you were even considering buying an Ogre and now we’ve left you contemplating your very existence in this ultimately-doomed universe, hear us out. Rim brake 29er rims — like the ones that you would need to have to make use of those canti studs in the first place — are becoming increasingly harder to find. We could have given you a feature that you’d end up not really being able to use in the future but what kind of monsters do you think we are? To quench your unquenchable thirst for rim brakes, check out the Troll.
As far as other updates to the frame go, that about sums it up. Ogre still has everything else you’ve come to know and love: two water bottle mounts, four sets of three-pack bosses, mid- and low-blade fork eyelets, threaded holes for racks, fenders, and trailer mounting nuts, and a Rohloff OEM2 axle plate slot. It still features horizontal-slotted dropouts with Gnot-Boost spacing, a tweaked non-suspension corrected geometry, and a beefy tire clearance. It’s still fully compatible with both 29 x 2.5” and 27.5+ tires. In the complete bike version, we’ve opted to go with a 1x drivetrain and a flat handlebar.
We typically try to avoid BS cliché terms like “Do-It-All” or “Swiss Army Knife of Bikes”, so we’ll just say that Ogre can probably handle most of the ideas that are bouncing around in your head.

Off-road touring can be a zesty enterprise, but it’s not without its perils. Bicycles are simple machines that are extremely efficient, but all simple machines carry along with them the chance of breaking down. This efficiency can get you in trouble if your bike decides to break down far away from the comforts of your parent’s basement. If you’re going to ride your bicycles where no one can see, you better take gear that’s up to the task. Troll is up to the task.
Our Troll was once a simple mountain bike frame with a few extras that made it nice for touring. The Troll has evolved into a frame that has been pushed deeper into the category of off-road touring. Its geometry is no longer suspension corrected, which gives it more room for a larger frame bag. We’ve also adorned this frame with our Gnot-Boost spacing, allowing you to use any mountain bike hub whether it be 135mm QR, 12 x 142mm thru-axle, or 12 x 148mm Boost hub. The chainstay yoke has been redesigned to be fully compatible with 26+ tires and the dropouts still allow you to run disc brakes, fenders, a Rohloff hub, and racks simultaneously. It also comes with more braze-ons than you thought possible – there are four triple bottle mounts on the fork alone (don’t get excited, you can only run one Anything Cage per fork leg), as well as two more triple bottle mounts on the down tube.
Troll is a bike that has one purpose – and that purpose is to carry you as far away from society as possible. Man has known for eons the call of the indifferent forest. The inexorable march of time, and dumb crap like cell phones, have dulled our senses and made us afraid. Reclaim your animalistic tendencies atop Man’s greatest invention.

If having fun for the sake of having fun sounds appealing to you, "going fat" will change the way you ride forever. The security and control that the wheel system found on our Fatboy SE provides is unparalleled. You get dramatically more traction, grip, and floatation than with traditional mountain tires, all without sacrificing much to climbing efficiency.
The end result is easy to explain—you have way more fun. And to make sure of it, we built the Fatboy with a durable, no-nonsense list of components that are low-maintenance and eager to perform season after season.
- The frame features an M5 alloy construction that provides the ideal blend of efficiency and durability, while the geometry creates a roomy top tube and short chainstays for easy climbing and confident descending.
- Our alloy fork with air-formed legs is lightweight and pairs up perfectly with the fat wheel system to soak up trail chatter and bumps.
- The Shimano 10-speed groupset features a wide gear range that delivers climbing and descending efficiency in spades. On top of this, the one-by setup is notorious for being next to impossible to drop a chain with, plus it provides significant weight savings in comparison to a standard two-by setup.

Every now and again, we're all faced with going on a diet, and the same is true for our Fatboy. With the new Fatboy Comp Carbon, we've elevated the fat bike platform to a higher level of performance, strength, and efficiency.
It features a sophisticated 10m carbon construction that's lightweight, ultra-compliant, and stiff in all the right places for the climbs. The layup also allowed us to integrate internal cable routing to keep things clean and simple through nasty conditions.
Sprinkle in a durable one-by drivetrain and some near bombproof alloy wheels, and you have a bike that will give new purpose to winter and more fun to springtime.
- An immaculate FACT carbon fiber construction ensures that the frame is lightweight and plenty stiff in all the right places. Internal cable routing is also incorporated; ensuring that slush, sand, snow, or dirt will have no bearing on performance out on the trail.
